PHP 中的 URL 解码

发布于 2024-08-12 09:12:24 字数 380 浏览 4 评论 0原文

我正在尝试使用 PHP 的 urldecode 函数解码此 URL 字符串:

urldecode("Ant%C3%B4nio+Carlos+Jobim");

这应该输出...

'Antônio Carlos Jobim'

...但相反,

'Antônio Carlos Jobim'

我已经在 基于JS的在线解码器取得了巨大成功,但似乎无法在服务器端执行此操作。有什么想法吗?

I am trying to decode this URL string using PHP's urldecode function:

urldecode("Ant%C3%B4nio+Carlos+Jobim");

This is supposed to output...

'Antônio Carlos Jobim'

...but instead is ouptutting this

'Antônio Carlos Jobim'

I've tested the string in a JS-based online decoder with great success, but can't seem to do this operation server side. Any ideas?

您的字符串也是 UTF-8 编码的。这将起作用:

echo utf8_decode(urldecode("Ant%C3%B4nio+Carlos+Jobim"));

输出:“Antônio Carlos Jobim”。

Your string is also UTF-8 encoded. This will work:

echo utf8_decode(urldecode("Ant%C3%B4nio+Carlos+Jobim"));

Output: "Antônio Carlos Jobim".

实际上,您得到了所需的输出,但它没有被解释为 UTF-8。如果这是在 HTTP 应用程序上,您应该发送标头或元标记(或两者),告诉客户端使用 UTF-8。

编辑:例如:

// replace text/html with the content type you're using
header('Content-Type: text/html; charset=UTF-8');

Actually, you get the desired output, but it is not interpreted as UTF-8. If this is on an HTTP application, you should send a header or a meta tag (or both) which would tell the client to use UTF-8.

Edit: for example:

// replace text/html with the content type you're using
header('Content-Type: text/html; charset=UTF-8');

当我

<?php
echo urldecode("Ant%C3%B4nio+Carlos+Jobim");
?>

在浏览器中正确显示时,就像

安东尼奥·卡洛斯·若比姆

我已经使用 XAMPP 进行了测试

when I do

<?php
echo urldecode("Ant%C3%B4nio+Carlos+Jobim");
?>

Its display correctly in my browser like

Antônio Carlos Jobim

I have tested with XAMPP

另一种选择是:

<?php
$smthing = 'http%3A%2F%2Fmysite.com';
$smthing = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($smthing)); 
$smthing = html_entity_decode($smthing,null,'UTF-8');
echo $smthing;
?>

输出变为:http://mysite.com

another option is:

<?php
$smthing = 'http%3A%2F%2Fmysite.com';
$smthing = preg_replace("/%u([0-9a-f]{3,4})/i","&#x\\1;",urldecode($smthing)); 
$smthing = html_entity_decode($smthing,null,'UTF-8');
echo $smthing;
?>

output becomes : http://mysite.com

在将其回显到页面之前,您是否也在使用 htmlenteties ?当我刚刚测试您的代码时,仅使用 urldecode("Ant%C3%B4nio+Carlos+Jobim"); 部分就可以正常工作,但是当我通过 htmlentities 运行它时我得到了和你一样的输出。

这似乎是 UTF-8 字符以及 PHP 如何处理 htmlentities 函数的问题。

Are you also using htmlenteties before echoing it to the page? When I just tested your code it worked fine with just the urldecode("Ant%C3%B4nio+Carlos+Jobim"); part, but when I ran it through htmlentities I got the same output as you did.

It seems to be a problem with the UTF-8 characters and how PHP handles the htmlentities function.
